Description

[Detailed Description of the Invention] (Technical Field) This invention relates to a cap for a container for dispensing liquids such as shampoo and detergent.

(Problems to be Solved by Prior Art and Invention) A so-called shift-open cap is known as a type of cap whose spout can be easily opened and closed.

FIG. 8 shows a shift-open type cap proposed in Japanese Utility Model Publication No. 54-32785.
This device has a spouting nozzle 41 protruding from the center of the top plate of the cap body 30, and a horseshoe-shaped operating lever 43 is attached to an annular member 42 fitted into the spouting nozzle 41 so as to be able to freely rise and fall. A plug portion 45 is formed on the lower surface of the spout 43 to close the spout 44 of the spout nozzle 41 when the operating lever 43 is raised. This type of cap has the advantage that it is easy to visually confirm whether it is opened or closed, there is little risk of misuse, and it is easy to manufacture.

However, if a liquid dispensing container with this cap attached is packaged in a cardboard box or the like and shipped, the liquid dispensing container may be damaged during transportation, especially if the top and bottom of the cardboard box are misaligned and the cardboard box is handled upside down. It is in a state where it is supported by the control lever 43 of the cap on the head, and if the cardboard box is shaken at this time, the control lever 43 is tilted by the force applied from the side, and the spout 44 of the spout nozzle 41 is tilted. There was a risk that the container would open and the contents of the container would spill out.

This idea was made in view of the above circumstances, and it can be used in a state where the spout can be opened and closed by tilting the optional operation lever, and it can be used even if it is not handled roughly during transportation, such as when the cardboard box is turned upside down. To provide a shift-open type cap that can easily switch between a lock state and a lock state in which an operating lever does not tilt and contents do not flow out.

(Means for Solving the Problems) In the cap of the present invention, a height is provided on the outer surface of the spout nozzle at a position opposite to the spout so that the operating lever can pass through but the stopper cannot pass through. An operating lever tilting preventing portion is provided so as to prevent the operating lever from tilting when the annular member is rotated to position the operating lever at the lock position. A gap is formed between the tilt prevention parts through which the stopper can pass, and when the annular member is rotated to position the operation lever at a position where the operating lever can be opened and closed, the stopper passes through the gap. By configuring the operating lever so that it can be tilted,
We attempted to solve the above problem.

(Function) In the cap of the present invention, when an attempt is made to tilt the operating lever that is in the locked position, the stopper collides with the operating lever tilting prevention portion, thereby preventing the operating lever from tilting (locked state).

On the other hand, when the annular member is rotated to position the control lever in the position where it can be opened and closed, the stopper can pass through the gap formed between the control lever tilt prevention parts, so that the control lever can be tilted. The spout can be opened as necessary (in use).

(Example) Hereinafter, the present invention will be explained in detail with reference to the drawings.

Embodiment 1 Figures 1 to 3 show the first embodiment of the cap of this invention, and the reference numeral 1 in the figures is made of relatively elastic synthetic resin such as polyethylene resin, which can be used by injection molding. This is the main body of the cap. As shown in FIG.
It's in a much more depressed state. In addition, the top plate part 2
The central part of the cap bulges high above the cap to form a spout nozzle 4. The spouting nozzle 4 has a substantially hemispherical shape, and a small-diameter hole is formed at its upper end to serve as a spout 5 .

The outer surface of the pouring nozzle 4 is provided with operation lever tilting prevention parts (hereinafter abbreviated as tilting prevention parts) 4A and 4A at two locations. The tilt prevention portions 4A, 4A abut against the plug portion of the operating lever, which will be described later, and prevent the operating lever from tilting. The tilting prevention portion 4A is a strip-shaped member formed by expanding the circumferential surface of the spout nozzle 4 outward, and its bulging height is such that the operating lever 11, which will be described later, can pass through. However, the plug portion 13 protruding from the lower surface is set to a size that cannot be passed through. The tilt prevention parts 4A, 4A are provided in contact with the spout 5 so that their longitudinal directions extend in the radial direction of the spout 5. Further, the two tilt prevention parts 4A, 4A are symmetrically provided at a distance of 180 degrees from each other with respect to the central axis of the nozzle 4. Further, a gap 17 is formed between these tilt prevention parts 4A, 4A, through which a plug part 13 of an operating lever 11, which will be described later, can pass.

At the base end of the pouring nozzle 4, there is an annular member 8, which will be described later.
An engaging convex portion 6 for locking is formed, and
Similarly, an annular member 8 is also provided on the inner surface of the upper end 3 of the side wall portion.
An engagement recess 7 for locking is formed.
This engagement convex portion 6 is cut out at two locations along the line connecting the tilt prevention portions 4A, 4A.
These notches serve as temporary stopping recesses 6a, 6a for determining the position of the annular member 8, which will be described later, in the circumferential direction of the pouring nozzle 4.

An annular member 8 is fitted into the annular groove-shaped top plate portion 2 formed by the upper end 3 of the side wall portion and the pouring nozzle 4 . The annular member 8, as shown in FIG. 3a,
It is disc-shaped, and its dimensions are similar to the above-mentioned groove-shaped top plate part 2.
has come to almost match. An engaging recess 9 that engages with the engaging convex portion 6 is formed on the inner surface of the annular member 8, and an engaging convex portion 10 that engages with the engaging concave portion 7 is formed on the outer surface thereof. Further, within the engagement recess 9, two temporary stop convex portions 9a, 9a that engage with the temporary stop concave portions 6a, 6a are provided at opposing positions. With these, the annular member 8 is attached to the cap main body 1 so as to be rotatable in the circumferential direction, and when the annular member 8 is rotated, a slight response can be felt at a predetermined position and the position can be known. It's becoming like that.

Further, on the upper surface 8c of the annular member 8, a horseshoe-shaped operating lever 11 is integrated so as to straddle the spout nozzle 4 of the cap body 1 and the tilt prevention parts 4A, 4A provided on the spout nozzle 4. It is provided. As shown in FIG. 3, this operating lever 11 is provided at a position where it is sandwiched between the temporarily stopping convex portions 9c, 9c of the opening/closing panel 8, and its base end is thin, and the hinge portion 12, It is said to be 12. The hinge portions 12, 12 allow the operation lever 1 to
1 can be raised and lowered with respect to the annular member 8.
It is desirable that the operating lever 11 and the annular member 8 be integrally molded from polypropylene resin or the like, which has a good hinge effect.

Furthermore, a hemispherical plug portion 13 that projects inward of the lever 11 is provided at the top of the lower surface of the operating lever 11 . This plug portion 13 is connected to the operating lever 11
has such a size and shape that it closes the spout 5 of the spout nozzle 4 when the operating lever 11 is raised.

In this cap, as shown in FIG.
The position matching the direction connecting A and 4A is the lock position. In this locked position, the plug portion 13 provided on the lower surface of the operating lever 11 strongly contacts the tilting prevention portions 4A, 4A, and the operating lever 11 is prevented from tilting (locked state).

In addition, in this cap, as shown by the dashed line in FIG.
The position where the direction in which the lever 17 extends and the direction in which the operating lever 11 is raised and lowered correspond to the opening/closing position. In this opening/closing position, the locus of movement of the stopper 13 as the operating lever 11 is raised and lowered coincides with the interval 17, so the operating lever 11 can be tilted and the spout 5 can be opened as necessary. The contents can be poured out (in use condition).

In this way, in this cap, on the outer surface of the spout nozzle 4, at a position facing across the spout 5,
In the vicinity of the spout 5, there are protruding anti-tilting parts 4A, 4A through which the plug part 13 cannot pass, so when the annular member 8 is rotated and the operating lever 11 is positioned at the lock position, Plug part 13 is tilt prevention part 4A, 4A
When the operating lever 11 is in a locked state where the operating lever 11 is prevented from tilting, and when the annular member 8 is rotated to position the operating lever 11 in the position where the operating lever 11 can be opened and closed, the gap 17 between the anti-tilting parts 4A and 4A is closed. The plug part 13 passes through and the operation lever 11 is ready to be opened and closed by tilting it at any time.

Therefore, by simply rotating the annular member 8 and setting the position of the operating lever 11 in a predetermined direction, this cap can be locked into a locked state that prevents the contents from spilling due to impacts during transportation, and can be opened and closed at any time. It becomes possible to switch between states.

In addition, a stopping recess 6 is placed on a line connecting the tilt prevention parts 4A and 4A of the engagement convex part 6 at the base end of the spouting nozzle 4.
a, 6a are provided, temporary stopping projections 9a, 9a are provided in the engagement recess 9 of the inner part 8a of the annular member 8, and the operation lever 11 is connected to the temporary stopping projection 9a, 9a.
9a, the opening/closing panel 8 is rotated so that the operating lever 11 is in the lock position (the state shown in FIG. 1) perpendicular to the line connecting the tilt prevention parts 4A, 4A of the nozzle 4. When it comes, the stopping recesses 6a, 6a and the protrusions 9a, 9a are once engaged, and a light response is obtained. Therefore, as described above, it is easy to set the operating lever 11 to the locked position where it cannot be tilted.

Embodiment 2 FIGS. 4 and 5 show a second embodiment of the cap of this invention, and the same components as the first example shown in FIGS. 1 to 3 are designated by the same reference numerals. to simplify the explanation.

The cap main body 1 of this example has a tilt prevention part 4 provided at a position sandwiching the spout 5 of the spout nozzle 4.
A, 4A are formed in a substantially semicircular shape, and therefore, the portion sandwiched between the tilting prevention parts 4A, 4A is groove-shaped and serves as a tilting guide groove 14. The operating lever 11 and ring member 8 shown in FIG. 3 are attached to the cap body 1.

The cap in this example also provides the same effects as the cap in the first example, and
When the operating lever 11 is set to the lock position perpendicular to the line connecting the tilting prevention parts 4A, 4A, the tilting guide groove 14 is covered and hidden by the operating lever 11, resulting in a favorable appearance.

Embodiment 3 Figures 6 and 7 show a third embodiment of the cap of this invention, and the same components as in the example shown in Figures 1 to 5 are given the same reference numerals. Let me simplify the explanation.

In the cap main body 1 of this example, an engagement groove 15 is provided at the lower end of the approximately semicircular anti-tilting portions 4A, 4A formed on the spout nozzle 4. This engagement groove 15 extends along the guide groove 14 along the circumferential direction of the nozzle 4.
It is formed at the same depth as , and further communicates with the tilting guide groove 14 between the tilting prevention parts 4A, 4A. The operating lever 11 and ring member 8 shown in FIG. 3 are attached to the cap body 1. In the case of the cap of this example, the operation lever 11 is tilted down along the tilting guide groove 14, and then the annular member 8 is rotated, and the stopper portion 13 of the operation lever 11 is rotated.
When the lever 11 is engaged with the engagement groove 15, the operating lever 11 will not rise.

The cap of this example can also provide the same effects as the caps of the first and second examples. then turn the operating lever 11
Since the spout 5 can be prevented from standing up, the spout 5 can be kept open at all times, which is convenient when the contents of the container are used frequently.

In the above explanation, the stopping recess 6
a and the convex portion 9a are provided so that a tactile sensation can be obtained at a position where the operation lever 11 is not tilted, but they may be provided at a position where the operation lever 11 can be tilted, or the tactile sensation can be obtained by other means. You can do it like this.

(Effects of the invention) As explained above, the cap of this invention is located on the outer surface of the spout nozzle at a position opposite to the spout.
An operating lever tilting prevention part is provided so as to prevent the operating lever from tilting when the operating lever is in the lock position by providing a protruding operating lever tilting prevention part having a height that allows the operating lever to pass through but prevents the stopper from passing through. In addition, a gap is formed between the operating lever tilting prevention parts through which the stopper can pass, and when the operating lever is in the open/close position, the stopper passes through the gap and the operating lever can be tilted. Therefore, when the control lever is in the lock position, the stopper collides with the control lever tilt prevention part to prevent the control lever from tilting, and when the control lever is in the open/close position, the control lever is prevented from tilting. Tilting operation is possible.

Therefore, the cap of this invention can be easily switched between the locked state, which prevents the contents from spilling due to impacts during transportation, and the operating state, which can be opened and closed at any time, simply by changing the direction of the operating lever.
